SPECIFICATION forming part of Letters Patent No. 292,388, dated J'anuarvQQ, 1884.- I Application filed December 12, 1883. (ModeL) To aZZ w/wm it mag concern Be it known thatI, WILTON TRIGG, of Cairo, in the county of Alexander, and in the State of Illinois, have invented certain new and useful Improvements in Beading and Molding Attachments for Planing-Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which Figure 1 shows a View inelevation of a rotary cylinder-planer with my beading attachment applied thereto; Fig. 2, a detail view of the attachment removed, and Fig. 3 a crosssection on line an ac of Fig. 1.

The object of my invention is to provide an improvement in beading and molding attachments for planers; and to this end it consists in the attachment as hereinafter described, and

more specifically set forth in the claims.

In the drawings, A designates the cylinder of a rotary planer. To this are attached the cutters or knives B B, slotted at O G, and adjustably held in place on the cylinder by means of set-screws D D, extending through these slots. In the drawings andmodel these setscrews are shown as provided with washers E E between their heads and thesurface of the knife; but such washers are of course not necessary. s I

As is usual in cylinder-planers, the portions of the cylinder between the parts to which the knives are directly attached are cut away or reduced insize, as shown, so that a longitudt nal groove, F, is formed in said cylinder "between the knives. WVithin this groove or concave portion of the cylinder-surface is fastened my beading attachment-G, consisting of the mainv attaching part H, curved to fit the groove or concave and slotted, as shown at I,

and the portion K extending up in front of and beyond the knife-edge b. tion II extends in a direction parallel to the axis of the knife-cylinder. A/setscrew, L, provided with washer M, extends through this slot and into the body of the cylinder. VVit-h' this arrangement of slot and set-screw the beading attachment can evidentlybe adjusted to a desired position along the cylinder and fixed at any adjustment. As shown, the attachment is curved to fit the concavities in the cylinder The slotxin the porsurface, and so that the beading or molding end rests against the under surface of the knife, near and at the edge of the latter, and is thus supported by it and prevented frombeing bent back when the planer is in operation. I contemplate using a series of these beading attachments on the same cylinder,but prefer to have each attachment in a different groove in the cylinder, and acting directly with a different knife, as indicated in the drawings. The shape of the operative end of the attachment,which projects beyond the edge of the knife, is of course to beef any form desired to'make any particular shape of molding'or beading,

I have shown my attachment as applied to a cylinder-planer. It obviously can be equally well applied'to other forms of planers in the same way without departing from my inven tion.

Having thus fully set forth the nature of my ing or molding attachment attached to said planer in front of a cutter, thereof, and supported near .its operative end, which projects beyond the edge of the cutter, by the under face of said cutter, substantially as shown and described. 7

2. In combination with the cutter of a planer, a beading or molding attachment fastened upon the surface of the planer in front of the cutter, and atits operative end bent up, so as to rest against the under face of the latter and be supported thereby, substantially as and for the purpose described.

3. In combination with a planer, a heading attachment adj ustably fastened upon the planer. in front of a knife, and at its operative end supported by the under face of the knife, substantially as and for the purpose set forth.

4. In combination with the planer-cylinder, the beading attachment adj ustably fastened to the cylinder in front of one of the knives by means of a set-screw passing through a slot in its attaching portion, and supported at or near its operative end by the knife, substantially as shown and described.

5. In combination with the cylinder, concaved or provided with longitudinal grooves adjustably fastenedwithin one of said grooves, screw extending through such slot into the 6 and at its operative end bent up, so as to hear cylinder-body, substantially as and for the against and he supported by the under face of purpose set forth. the knife on the rear side of the groove, sub- In testimony that I claim the foregoing I I 5 5 stantially as and for the purpose set forth. have hereunto set my hand this 27th day of 6. Ineombinationwith thegroovedeylinder October, 1883. carrying the cutter-knives, the heading or molding attachment hevingits main or attaching portion bent to fit the concavity of the 10 groove, and provided with the slot extending parallel to the axis of the cylinder, and the set- WI'LTOX TRIG G.
